In Arizona, you are not always legally required to hire a professional process server — but there are compelling reasons why it's almost always the right choice.
In Arizona, the plaintiff (the party bringing the lawsuit) cannot serve the defendant themselves. Service must be performed by a third party who is 18 or older and not a party to the case.
Some Arizona courts and case types require or strongly prefer service by a certified process server, especially for protective orders and out-of-state service.
When a defendant is avoiding service, a professional process server has legal tools, skip tracing capabilities, and the experience to effectuate service that a layperson does not.
